Follow these four guidelines when positioning your keywords:
Frequency counts
Sprinkle your keywords throughout your title, meta tags, alt text, image names, and the actual text on your pages. The more frequent the keyword, the more relevant the page will appear to search engines. Beware, however, of overdoing it. If more than 10-15% of your words are keywords, search engines will assume you're trying to trick them and may penalize you.
Use your title tag
Search engines assume that pages with search terms in the title tag are more relevant than other pages, so it's critical to include two or three keywords in your page's title. But don't just list keywords! Your title will appear in search results and users' bookmarks, so try to make it both enticing and readable.
Avoid spam
Don't want to get banned? Then don't use keywords that don't match the content of your page; don't list keywords for the sake of listing keywords; and don't repeat the same keyword in your meta tags. Search engines consider these practices spamming and will penalize you!
Location matters
Any page relevant to a topic will usually mention the search terms immediately. Your keywords should appear near the top of your page content or in the first few lines of text. This same rule applies to your title and meta tags: Make sure the most important keywords appear first.
Making your content keyword-rich and well-organized is the first step to getting noticed by search engines. If you don't see results, experiment with your keywords, then tweak your content and meta tags.
Remember: Getting good search engine rankings is an ongoing, evolving process, and it takes time, creativity, and, most important, flexibility! Learn more about promoting your site.
